中线蝶阀选型及安装说明

Characteristic 特点

1. 小型轻便，容易拆装及维修，并可有任意位置安装。Miniature and exquistie, easily assembled and disaaembled and repaired, mountable at any position.

2. 结构简单，紧凑，90回转启闭迅速。Simple and compact structure, quick open-close in 90 rotation.

3. 操作扭矩小，省力轻巧。Small operation torque, saving labor and exquisite.

4. 流量特性趋于直线，调节性能好。The flow property comes towards linear and holds a good adjustable performance.

5. 启闭试验次数多达万次，寿命长。The open-close test has been made up to ten thousands of times, a long duration.

6. 达到完全密封，气体试验泄漏为零。Completely sealed, with a zero leak via the gas test.

7. 选择不同零部件材质，可适用多种介质。Different material used with the parts can be suitable for various media.

1. 法兰之间的空隙应当允许阀板半闭状态的阀进入，这样在安装过程中及初次打开阀门的时候阀座边缘将被保护并且密封圈内侧将缩小。

2. 在调整好阀门与管道法兰的位置后及旋紧螺栓之前，阀板应置于完全打开位置。如果阀板处于关闭状态，密封圈可能被扭曲、挤压膨胀并包住阀板边缘，在实效打开时造成极大的力矩。阀座可能因此撕扯、扭曲造成性的损害。

3. 在安装蝶阀时，如果法兰未能给予蝶阀充分的空间将会损坏密封圈。

1、 The separation between the flanges should allo free access to the valve with the disc half closed, when the valve open, the rim will be protected and the initial sealing is reduced during the istallation.

2、 After aligning the valve with the tube flanges, and before tightening the bolts, the disc should be turned until it completely opened. If it were closed it would twist the ring, so it would expand round the edge of the disc, which would create and excessively high torque in the initial opening.

3、 If the flanges are not sufficiently separated they cold damage the elastic ring.
